The maximum number of ribbon connections is limited

[zhangjh-art]

here is my config:
ribbon.MaxTotalConnections=500
ribbon.MaxConnectionsPerHost=3000

Zuul version is 1.x
I found that the maximum number of connections configuration failed，For example, the qps of one of my services is 8000. Now I have deployed the services in a cluster, but the qps are still 8000. I have deployed an additional zuul to enable nginx to forward. I find that the qps are still not improved. I have counted the connections of each application service and found that the total is unchanged, with only about 100 active connections.

Does anyone know why？thanks！
